Monga zigawo zazikulu, mabuloko a masilinda a injini ndi mitu ya masilinda ziyenera kupirira kutentha kwambiri ndi kupsinjika, kuonetsetsa kuti zikugwirizana bwino, komanso kupereka mgwirizano wabwino. Zizindikiro zawo zaukadaulo, kuphatikizapo kuyesa kuuma ndi kuyesa kulondola kwa miyeso, zonse zimafuna kuwongolera mwamphamvu pogwiritsa ntchito zida zolondola. Kuyesa kuuma kwa mabuloko a masilinda ndi mitu kumagwiritsidwa ntchito makamaka poyesa mawonekedwe a makina a zipangizo, kuonetsetsa kuti zikukwaniritsa zofunikira pa kapangidwe.
Mayeso a kuuma kwa Rockwell ndi oyenera kuwunikira kuuma kwa malo akuluakulu, athyathyathya monga mapulaneti a silinda (monga malo olumikizirana ndi mutu wa silinda, pansi pa silinda) ndi nkhope za mabowo a crankshaft. Kuti muwone bwino pa intaneti pa mizere yopangira, zofunikira zoyesera zomwe zasinthidwa zitha kuperekedwa. Mayeso a kuuma kwa Rockwell okha amatha kuphatikizidwa ndi mzere wopanga kuti akwaniritse ntchito yopanda munthu, yokhala ndi magwiridwe antchito apamwamba komanso zotsatira zokhazikika. Njira yoyesera iyi ndiyo yomwe imagwiritsidwa ntchito kwambiri popanga zida zamagalimoto ndipo imagwirizana ndi miyezo ya ISO 6508 ndi ASTM E18.
Mayeso a kuuma kwa Brinell amagwiritsidwa ntchito poyesa kuuma kwa malo opanda ma cylinder block ndi zigawo zokhuthala (monga ma cylinder block sidewalls), ndipo ndi oyenera kwambiri poyesa ubwino wa kuponyera ndi mphamvu ya kutentha kwa ma cylinder steel steel. Dziwani kuti mayeso a Brinell amasiya mabala akuluakulu, kotero ayenera kupewedwa pazinthu zomwe zimawonongeka mosavuta monga malo amkati mwa makoma a cylinder ndi malo opangidwa ndi makina olondola.
Ma Vickers hard testers ndi oyenera kuyesa kuuma kwa zigawo zopyapyala za aluminiyamu alloy cylinder blocks, malo amkati a cylinder liner (kuti asawononge malo otsekera), komanso kuyesa kuuma kwa zigawo ndi zokutira zotenthedwa ndi kutentha (monga zigawo za nitride, zigawo zozimitsidwa) pamalo a cylinder block. Njira yoyesera iyi ikukwaniritsa zosowa zoyesera molondola za injini za ndege ndi zamagalimoto apamwamba, ndipo ikutsatira miyezo ya ISO 6507 ndi ASTM E92.
Malinga ndi mabuloko a masilinda ndi mitu ya masilinda opangidwa ndi zipangizo zosiyanasiyana, miyeso yolimba yotsatirayi ikhoza kutchulidwa:
| Chigawo | Zipangizo Zofala | Mtundu Wofotokozera Kuuma (HB/HV/HRC) | Cholinga Choyesera Chachikulu |
| Chitsulo Choyimitsa ... | HT250/HT300 (Chitsulo Chopaka Imvi), Chitsulo cha Graphite Chozungulira | 180-240HB20-28HRC | Onetsetsani kuti kukana kuvala ndi kukana kusintha kwa mawonekedwe |
| Aluminiyamu Aloyi Cylinder Block | A356+T6, AlSi11Cu2Mg | 85-130 HB90-140 HV 15-25 HRC | Kulimbitsa mphamvu ndi makina |
| Tayani Chitsulo cha Silinda Mutu | HT200/HT250, Chitsulo Chodulira | 170-220 HB18-26 HRC | Pitirizani kukhudzidwa ndi kutentha kwambiri ndipo onetsetsani kuti pamwamba pake pali kulimba |
| Mutu wa Silinda wa Aluminiyamu Aloyi | A356+T7, AlSi12Cu1Mg1Ni | 75-110 HB80-120 HV 12-20 HRC | Sungani bwino katundu wopepuka, kutentha kotentha komanso mphamvu ya kapangidwe kake |
Malinga ndi zofunikira zosiyanasiyana zoyesera za mabuloko a masilinda a injini, Laizhou Laihua ikhoza kupereka mayankho okonzedwa kutengera zinthu zinazake. Izi zikuphatikizapo mitundu yokhazikika, mitundu yokonzedwa ya mitundu yonse ya zoyesera zolimba za Rockwell, Brinell, ndi Vickers, komanso kapangidwe ka zida zapadera zopangidwa kuti zigwirizane ndi zinthu—zonse cholinga chake ndi kupititsa patsogolo magwiridwe antchito oyesera komanso kulondola kwa muyeso.
